Vietnamese students won 6 medals at the International Mathematical Olympiad

With 2 gold medals, 3 silver medals, 1 bronze medal, and a total score of 188, the Vietnamese team ranked 9th out of 113 countries and territories participating in the 66th International Mathematics Olympiad (IMO).

According to the Ministry of Education and Training , all six students of the Vietnamese national team won medals at the 66th International Mathematics Olympiad (IMO) in 2025, held in Sunshine Coast, Queensland, Australia.

With 2 Gold medals, 3 Silver medals, 1 Bronze medal, a total score of 188, the Vietnamese team ranked 9th out of 113 countries and territories participating in this year's competition, after the following delegations: China (1st), the United States (2nd), South Korea (3rd), Poland and Japan tied for 4th, Israel (6th), India (7th), Singapore (8th).

Specifically, the two students who won the Gold medals were: Vo Trong Khai, grade 12, Phan Boi Chau High School for the Gifted, Nghe An province; Tran Minh Hoang, grade 12, Ha Tinh High School for the Gifted, Ha Tinh province.

The Silver Medals went to: Nguyen Dang Dung, grade 12, High School for Gifted Students in Natural Sciences , University of Natural Sciences, Vietnam National University, Hanoi; Nguyen Dinh Tung, grade 11, High School for Gifted Students in Natural Sciences, University of Natural Sciences, Vietnam National University, Hanoi; Le Phan Duc Man, grade 12, Le Hong Phong High School for Gifted Students, Ho Chi Minh City.

Student Truong Thanh Xuan, grade 11, Bac Ninh High School for the Gifted, Bac Ninh province won the Bronze medal.

This year, the Vietnam Math Olympiad Team has the participation of students from the three regions of North, Central and South. Notably, the team has a female student in grade 11 participating and excellently winning a Bronze medal, that is Truong Thanh Xuan.

Compared with the results in 2024 (2 Silver medals, 3 Bronze medals and 1 Certificate of Merit), the achievements of the Vietnamese delegation in 2025 have clearly surpassed.

The 66th International Mathematical Olympiad was held from July 10-20, 2025 with the participation of more than 639 contestants. This is the second time Australia has hosted the IMO, after the first time in 1988. The total number of medals of the Competition includes: 72 Gold medals, 104 Silver medals, 145 Bronze medals.

The IMO 2025 exam consists of 6 problems: 2 arithmetic problems, 2 combinatorial problems, 1 geometry problem and 1 algebra problem (with combinatorial statements and combinatorial thinking requirements). This shows the tendency of this year's exam to focus on combinatorial content.

Notably, the only geometry problem in the exam, problem number 2, was proposed by Vietnam and the author was Mr. Tran Quang Hung, a teacher at the High School for Natural Sciences, University of Natural Sciences, Vietnam National University, Hanoi.

This is the fourth time Vietnam has had a problem selected for the official IMO exam, after 1977 (author Phan Duc Chinh), 1982 (author Van Nhu Cuong) and 1987 (author Nguyen Minh Duc).

The closing ceremony and award ceremony of the Competition will take place at 4:00 p.m. on July 19, 2025 (local time) in Australia.
